American Utility Metals 3CR12® Stainless Steel
Categories: Metal; Ferrous Metal; Stainless Steel

Material Notes: 3CR12 is a weldable ferritic stainless steel, specifically designed for aggressive material handling applications. It is intended to provide the benefits of traditional stainless steel, such as strength, corrosion and abrasion resistance, durability and low maintenance. But it is also able to provide additional benefits such as good weldability and formability, making it capable of fabrication by conventional techniques.

Because 3CR12 does not depend upon expensive alloying elements like Nickel and Molybdenum, it has maintained a consistently low cost advantage compared to other corrosion resisting materials. It also offers the option to reduce costs through eliminating protective treatments and corrosion allowances. In service, utility stainless steel goes on to generate savings in maintenance, improved productivity and longer service life. It is proven to offer lower life cycle costs than traditional materials where corrosion or abrasion affect service conditions.
